WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
Use the conventional procedures to measure wheel alignment.
1. CAMBER
Standard value:
–1
00’ ± 30’ (difference between right and left
wheel: less than 30’) or
–2
00’ ± 30’ (difference between right and left
wheel: less than 30’)
Select the camber angle as follows.
If the arrow on the bolt that couples the strut assembly
to knuckle faces inboard → –1
00’ ± 30’.
If the arrow on the bolt that couples the strut assembly
to knuckle faces outboard → –2
00’ ± 30’.
2. CASTER
Standard value: 3
54’ ± 30’ (difference between right
and left wheel: less than 30’)
NOTE
The suspension system is designed so as to retain the
preset caster value, requiring no adjustment for caster.
